How to get started if you want to learn German? What to do to practise your skills? Some of the most useful websites (all free!) to learn German are introduced here, including information on how to use them effectively:
A free website where you can learn Spanish, German, English, French etc., mostly by 
translating sentences. A game-like learning tool where you earn XP to level up – this makes it addictive!
How to use: You should set a goal for yourself, e.g. “100 XP a day” or 50 or… this depends on your time. Also, use the timed practice option (you can buy this for lingots) to earn XP faster and to srengthen your skills.
Lots
of free resources like articles and online courses, Videos, news, …
How to use: 10 to 20 minutes a day immersion with videos, Mp3s, articles etc. DW has content for all levels. Tip: Langsam gesprochene Nachrichten.
Write your own texts in German and get them corrected by native speakers. You will strengthen your knowledge of the language by actively using it.The groups also give you the opportunity to interact with other learners or native speakes of your target language.
How to use: Write at least one text a week, or some short ones 3-4 times a week, these can be three sentences about your day. Another useful tip is to write down little dialogues (or monologues) that you were saying throughout the day (probably in your mother tongue..but this way you will learn how to say these things in German!).
Of course there are more great websites out there for learning German, but those 3 get you started and also give you the ability to learn independently. Los geht’s!
